What is this test?
The 3-Hydroxymyristoleylcarnitine (C14:1-OH) test measures the amount of a specific fatty acid metabolite called C14:1-OH acylcarnitine in the amniotic fluid that surrounds the unborn baby. Acylcarnitines are substances produced when the body breaks down fatty acids for energy. This test is part of newborn metabolic screening and can also be performed during pregnancy using amniotic fluid to detect potential metabolic disorders in the fetus.
How is the test performed?
During amniocentesis, a small amount of amniotic fluid is collected from the uterus using a thin needle under ultrasound guidance. The fluid sample is then sent to a laboratory where it is analyzed using specialized equipment to measure the levels of various acylcarnitines, including C14:1-OH. The procedure is typically performed between 15-20 weeks of pregnancy.
Why is this test important?
This test helps healthcare providers evaluate how well the fetus is metabolizing fatty acids. Abnormal levels of C14:1-OH may indicate a fatty acid oxidation disorder, which is a group of genetic conditions where the body cannot properly break down fatty acids for energy. Early detection allows for prompt treatment after birth and can prevent serious complications.
